Initial velocities for the cytochrome c peroxidase-catalyzed oxidation of ferrocytochrome c by hydrogen peroxide have been measured as functions of both the ferrocytochrome c concentration (0.81-90uM) and hydrogen peroxide ...

Previous studies of hydrogen peroxide interaction with oxidized cytochrome oxidase showed a lack of uniformity and consistency. Problems arose from the use of heterogeneous enzyme (isolated at pH 7.0-7.4) and a large excess ...

Two separate optical conformers that are referred to as "430 nm" and "414 nm" are known for cytochrome c oxidase. Another two separate conformers are observed upon the binding of cyanide and are referred to as "rapid" or ...

Previous characterization of P. megasperma mitochondrial DNAs revealed two genic inversions between a host-specific and a nonspecific strain. As part of a characterization of oomycete mitochondrial genomes, studies of the ...

Incubation of resting cytochrome c̲ oxidase at low pH has two effects: 1) a blue shift of the Soret band to higher energy wavelengths with the occurrence of an isosbestic point, and 2) a fast to slow cyanide binding ...
